The reservoir .nions'or crank shaft may be fixedly held on the frame of the cycle or vehicle in any suit- :Fig'. 1, a very convenient arrangement being I I inders a which by the arrangement before deably eld closed normally under the action v of spiral springs Z and are positively operated upon spindles m upon. which also toothed operation of the exhaust valve and the valve as required according to the four ithout departing from the v I042! a combustion charge through the hollow crank shaft on-trunnion cl and that the ill-.-

or storage chamber g it will be understood is formed as a part of the retating frame a, being connected to the respective cylinders by the inlet pipes 1 ,which may be of suflicient strength to contribute to the stability of fixture of the storage chamber or reservoir aforesaid.

The charge may advantageously pass through a non-return valve from the storage chamber or reservoir on the suction stroke, or instead no such valve may be employed. 0r again, automatically operating means may be employed operable by means of a governor, or by centrifugal lorce.

In the illustrated construction the inlet pipes r are extended into-'the storage chamer and carry a double beat valve to which is carried upon a valve rod a which latter has provided at its outer extremity a weight y. The valve to is normally maintained open by means of the spring 2 and it is closed upon the attainment of a predetermined excessive speed of rotation ot the cylinders whereby t 1e rotation is thus regulated and racing prevented.

Ignition plugs 8- may be provided at the end of each cylinder for making contact With high tension metallic contacts and a silencer t consisting of a perforated pipe t and a perforated cylinder t in communication therewith may be provided in a position diametrically opposite to the storage chamber or reservoir Q aforesaid, which latter may be connected by means of pipes at to the exhaust valve casings or the exhaust valve out-- let of the respective cylinders a as illustrated. The outlet from the silencer t is provided in the outer end thereof as indicated.

A belt pulley 'v is mounted upon the cylinders for communicating movement to the driven parts; or a gear wheel chain wheel or other device maybe employed forthe same purpose,

In Fi 4 meansare illustrated for counteracting t e tendency of the inlet and exhaust valves to openo'n an excessive speed being attained b the motor. These means consistof two evers w pivoted at'sc upon a pin or spindle secured upon the wall of the cylinder. The outer extremities of these respective levers-are weighted, while their inner extremities engage respectively with the springs of the-valve spindles, so that on the rotation of the motor the weighted ends of the levers will tend to move upwardly and thus compress the springs with which they engage and thus draw the valves down upon their seats with a greater pressure than the normal pres sure with the springs aforesaid.

In the design of. an engine as hereinbefore described it will be understood that the necessity of an independent fl ywheel is obviated, and that the disposition of metal in the circular casing-may be such as to insure uniformity in the rotation of the casing and of the accumulation of such momentum as iectively air cooled, but with a view to render the cooling even more complete and effective the cylinders may be provided'with a casing having an inlet and an outlet for air, the former advantageously being disposed in front of the casing while the latter is disposed in the rear.

One advantage of the arrangement of the storage chamber and silencer in the manner hereinbefore described is that the metal is more or less uniformly distributed.

Furthermore it is obvious that more than two cylinders maybe employed.

What I claim as my invention and desire to secure by Letters Patent is 2-- 1. In combination, an internal combustion motor of the rotating cylinder type having two cylinders disposed in line, a closed crank chamber between said cylinder in which the explosive mixture is drawn, a chamber communicating with said crank chamber in which the explosive mixture is accumulated, said chamber being radially disposed with reference to said cylinders with pipes connecting said chamber to the respective inlet valve casings of said cylinders and a silencing ex hau'st chamber also radially disposed with reference to said'cylinders, and pipes leading therefrom to the respective exhaust valve casings of said cylinders substantially as de scribed.

2. In combination, an internal combustion motor of the rotating cylinder type having two cylinders disposed in line, a closed crank cham or between said cylinder in which the explosive mixture is drawn, a chamber communicating with said crank chamber in which the explosive mixture is accumulated, said chamber being radially disposed with reference to said cylinders With'pipes connecting said chamber to' the respective inlet valve easin s of said cylinders, a silencing exhaust cham er also radially disposed with referenceito said cylinders, and pi es leading therefrom to the respective ex aust valve casings of said cylinders, said exhaust chamberbeing constructed of an outer cylindrical caslng and an inner cylindrical easing intowhich the said pipes discharge, and an outlet from said inner casing at the inner end there-.
